Problem Description:

Due to a memory leak issue we need to upgrade the software of our router swiEZ3 tomorrow evening, Thursday July 27th 2017, between 19:00 and 21:00.
The upgrade will take around 30 minutes, and during that time all traffic will be re-routed to alternate paths, where available.
Thus for most sites, there will be no impact except that there will be no more redundancy for the duration of the upgrade.
The Cloudsigma peering will be totally interrupted, as there is no back up.
